I'm very happy to have encountered el-recodo.com! Great reference, with all the additional information!
I was searching Que falta que me hacés from Miguel Caló, very very well known. It's not in your database :-)

Dear friends, an improvement here... The lyrics page disappeared. Instead, the database is combined into this music page. As a result, it is now possible to perform advanced searches including composers, authors and lyrics extracts, combined with usual recording data (orchestra, singer, title...). Enjoy!
